In the new flanger the lever and man-power are dis-pensed with entirely, and a single air-brake cylinder and 60lbs. pressure of compressed air made to do the work of severalmen. The ploughs are hung underneath the car in the usuallocality ; but instead of being suspended from levers placedon the car floor, these ploughs are hung to a double rocker armplaced underneath the car floor framing, to which the air cyl-inder has its piston directly CO - p OW K m BO a 35O o iso o CS oH r-< 05 o a - « j 5ca Vol. LX1X, No. AND RAILROAD JOURNAL. 87 The control of the compressed-air cylinder lies in a three* way OOCk, w-herewith air is admitted to either end Ol the cyl incler and exhausted therefrom at will of the operator, who sua upon a kiiul of deck or look-out house liuilt 00 top of the car,much in the same manner that Borne freight cabooses are con-structed. Bj means ol compressed air and the three-way cockthe entire control of the Banger is put within the limit of onemans capabilities. All the lever hands are dispensed with, and the Banger man sits up there in his little look-out house running the ploughs closer to, and putting them down againmuch cpiieker after passing an obstruction than was ever doneby a hand-operated machine. Only a man or two need besent out with the operator on a Hanger, and they will be re-quired only in ease of accident. Air is taken from the train pipe
